FOUNTAIN COMB Filed June 1, 1938 A iiorneys Patented July 4, 1939 UNITEDSTATES PATENT ori 2 Claims.

This invention relates to a fountain comb, the general object of theinvention being to provide the comb with a reservoir at its upperportion for receiving various kinds of solutions for the treat- 5 mentof the scalp, with manually controlled means for causing some of thesolution to pass from the reservoir to the tooth carrying edge of thecomb.

This invention also consists in certain other features of constructionand in the combination 1,0 and arrangement of the several parts to behere- "2 ure 1.

Figure 3 is an enlarged fragmentary vertical sectional view showing thevalve means.

In this drawing the letter A indicates the comb and the letter Bindicates thereservoir the lower 5 edge of which is connected with. theupper edge of the comb in any suitable manner. One end portion of thereservoir is made of greater height than the rest of the reservoir andthis high part is formed with the two spaced upwardly extend- 30 ingparts preferably shaped as shown, these parts forming a recess 2, thebottom of which is formed with an opening 3 closed by a cork 4 which iscemented in place. Below the recess the comb is formed with an opening 5in which is 35 cemented a cork 6 which has a longitudinally extendinghole or bore 1 therein which leads from the reservoir through the loweredge of the body of the comb.

A plate 8 extends across the bottom of the recess 40 2 and across thetop of the cork 4. A valve rod 9 passes through a hole in the plate 8and through a hole in the cork 4 and said rod also passes through thebore 1 of the cork 6 and has a valve 7 disk ill at its lower end forclosing the lower end 45 "of the bore 1. The upper end of the rodextends above the plate 8 but terminates short of the plane of the toppart of the portions I so that these parts I prevent the valve rod beingdepressed to open the valve Ill by accident, such as 50 the upper partof the reservoir being struck by an object or pressed against an object.A button II is connected with the upper end of the valve rod forfacilitating the depression of the rod and a spring l2 encircles theupper portion of the rod 55 and has one end bearing against the button Hand the other against the plate 8. A small cylinder I3 is located in thespace between the two corks and the valve rod passesthrough thecylinder. The valve rod carries a piston it of leather orthe like whichoperates in the cylinder r and the upper open end of the cylinder isformed with the notches l5 and its lower end is outwardly bowed as shownat lfiand provided with a central port l6 through which the valve rod iiextends, said port 16' being slightly larger than the rod 9 for apurpose presently seen. This ported end it: is spaced from the cork 5when the upper end of the piston is engaging the cork sand in axialalignment with the bore 1; I A filling opening is formed in a part oftheZi-lfi reservoir and is closed by a plug ll" 50 that by removing theplug, tonic or other solutions can be placed in the reservoir and thenthe plug is closed. Then when it is desired to place some of thesolution on the scalp theu'ser presses'uponifli the button ll tolowerthevalve rcd'i which 20 opens the valve I9 and on the first part of thedownward movement of the stem the frictional engagement of the piston Mwith the cylinder 13 will cause'the cylinder to move clownwardlyf-iuntil its lower ported end I6 rests upon the cork 6 with the port- Itregistering with the bore 1. Then further'downward movement of the valverod will cause the piston M to eject some of the solution in thecylinder through the port I and past the valve I0 upon the scalp orother part of the body over which the comb is being drawn. Then when thebutton is released the spring l2 returns the parts to the normalposition and on the first part of this upward movement of the valve rodthe cylinder It will move upwardly with the piston l4 until its notchedend strikes the cork 4 when further movement of the cylinder will beprevented and then as the valve rod continues its upward movement thepiston M will draw some of the solution into the bottom of the cylinderthrough the port I6. Of course, the notches I5 prevent air being trappedin the top of the cylinder by the piston.

The teeth of the comb at the point where the opening 5 is formed arespaced a greater distance apart than are the other teeth and these twoteeth are made larger as shown at 58 to protect the smaller teeth whenthe device is being used to apply solution to the scalp or other part ofthe body.

While I prefer to use corks 4 and 6 for closing the upper and loweropenings it will, of course, be understood that any other suitablematerial can be used for these members and such mem- 56 bers can be ofresilient material so that the valve plate l will make a fluid tightjoint with the lower end of the member 6 and the stem will have asliding fluid tight passage through the upper member 4. The plate 8, ofcourse, prevents the spring from embedding itself into the top part ofthe member 4.

As will now be seen, I have provided a fluid measuring cylinder 13endwise movable in the reservoir B in opposite directions, respectively,under similar movement of the valve rod 9 and between opposite limits ofmovement established by engagement thereof with the corks 4 and 6, the

ported end l6 of the cylinder being opposed to the bore 1 in one limitof movement of said cylinder so as to block communication between saidbore and the reservoir B and so as to provide for ejection of themeasured amount of fluid from the cylinder through said bore under theaction of the piston l4, the ported end [6 of said cylinder being spacedfrom said bore I in the other limit of movement of the cylinder for thefilling ofthe cylinder through the port 16' with a uniform amount offluid each time the valve rod 9 and piston 14 are operated by the springl2.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A fountain comb comprising a back having a toothed edge and adischarge duct extending therethrough for conveying liquid to said edge,a liquid-containing reservoir on said back with which said ductcommunicates, and means to eject a measured amount of liquid out of saidduct comprising a liquid-measuring cylinder endwise movable in thereservoir between opposite limits of movement and having a ported endopposed to said duct in one limit of movement of said cylinder to blockcommunication between said duct and reservoir and provide for ejectionof fluid into the duct directly from said cylinder,

said ported end in the opposite limit of movement of the cylinder beingspaced from said duct for the filling of the cylinder therethrough fromthe reservoir, and a plunger extending into said reservoir and cylinder,said plunger being manipulative inwardly of the cylinder to move thesame into the first-mentioned limit of movement thereof and subsequentlyeject the fluid therefrom through said ported end and into said duct,and being tensioned for movement outwardly of said cylinder to move thelatter into said opposite limit of movement thereof and subsequentlydraw fluid from the reservoir into the cylinder by way of the ported endof the latter.

- 2. A fountain comb comprising a back having a toothed edge and adischarge duct extending therethrough for conveying liquid to said edge,a liquid-containingv reservoir on said back with which said ductcommunicates, and means to eject a measured amount of liquid out of saidduct comprising a liquid-measuring cylinder endwise movable in thereservoir between opposite limits of movement and having a ported endopposed to said duct in one limit of movement of said cylinder to blockcommunication between said duct and reservoir and provide for ejectionof fluid into the duct directly from said cylinder, said ported end inthe opposite limit of movement of the cylinder being spaced from saidduct for the filling of the cylinder therethrough from the reservoir,and a plunger extending into said reservoir and cylinder, saidrplungerbeing manipulafluid from the reservoir into the cylinder by way of theported end of the latter, said plunger ex--' tending through said ductand having an enlarged end coacting with said back to establish anoutward limit of movement of the plunger and simultaneously close theouter end of the duct to prevent leakage of the fluid therefrom.
